The 1945 Magni-Magic Code-O-Graph was manufactured in late 1944. Materials reestrictions were in force, and copper and brass were unavailable, so the badge body was made of stamped sheet steel that was overcoated with "gold" paint to make it look similar to the first two units. The Code-O-Graphs were in limited production, and the sponsor ran out of them, the only model where this happened.
